What is the most painful thing in the world? You are obviously rich but you can't show it off, you are obviously armed but you can't beat people up, you are obviously a supreme being but you can't show off proudly? None of the above, when you meet Xiao Hua, the real pain comes. He is the terminator of the immortal saints and the nightmare of gods and demons. His appearance brought deathly silence to the entire universe. The masters were dejected, the powerful people were lifeless, and countless strong men became insane, but they couldn't die... Ps: If you don't laugh, I'll tickle you.
